If their stock and real-estate market continue to tank, expect more disappearance.
“China runs their own ‘preemptive detention centers’. Several execs of well-known financial companies also disappeared recently. Playing markets at state’s expense, or any suspicion of it, guarantees long stay at such a place. Stashing money away from China would also qualify.”
My first thought was, Communists always viewed the rich as the problem. Take their wealth and your problem, (caused by them being rich) is solved. Since this is a wide-scale phenomenon it has to be the Chinese government doing it. So, yes, these guys are likely being detained while interrogators gain access to their wealth and -tax- it.
If Bernie Sanders and Hillary Clinton could do that here, they would.
